  • Piston-connecting rod-crank systems are widely used in many systems such as reciprocating internal combustion engines and reciprocating compressors. There are parts in the piston connecting rod mechanism that operate in connection with each other, such as piston, ring, piston pin, and connecting rod.

It does not include any improvement made in piston-cylinder frictions, however, it includes a structure that is complex and difficult to use. It also does not include a system for preventing the oscillating movement of the connecting rod. This system is not a system for eliminating piston-cylinder frictions, and it is not possible to use the lower part of the piston for extra compression.
  • the most important object of the present invention is to prevent the oscillating movement of the connecting rod and to eliminate the piston-cylinder thrust-side.
  • Another object of the present invention is to ensure that more efficient compressors and piston engines can be obtained by using the lower part of the piston in compression processes by means of to the linear movement of the connecting rod.
  • Yet another object of the present invention is to collect the frictions formed in the crank region on the bearing systems, thereby preventing the friction losses that occur in such mechanisms.
  • Yet another object of the present invention is to develop a piston-connecting rod-crank mechanism that can be applied to all kinds piston engine and compressor systems.
  • Yet another object of the present invention is to develop a system, in which the number of pistons can be increased in order to provide a more balanced and high-pressure system. Even higher pressure and balanced designs can be made by increasing the number of pistons (3 or 4 pieces).
  • Yet another object of the present invention is to provide a compression process as a result of 180 degrees rotation of the crankshaft and to obtain higher pressure systems by means of using the lower part of the piston for compression work.

  • Said system comprises piston (1 ), cylinder (2), connecting rod (3), suction and compression valves (4), ball bearing (5), needle bearing (6), rotor (7), crank shaft (8), upper cover (9), lower cover (10), sealing element (1 1 ), body (12), and hinge housing (13).

  • the piston (1 ) and the connecting rod (3) are designed to be a single-piece, unlike the conventional crank connecting rod mechanism. An extra piston pin was not required. Thus, the oscillating movement of the connecting rod is prevented and the lower side of the piston (1 ) is used for the compression process. Two flat compression rings are placed on the top and lower parts of the piston (1 ) in order to prevent pressure leaks in the suction and compression processes during the up-and-down movement of the piston (1 ).

  • FIG. 1 illustrates the mechanism of the present invention designed for balanced twinpiston high-pressure compressors.
  • both the upper and lower parts of the piston (1 ) are used for suction (A) and compression (B) processes since the connecting rod (3) that connects the piston (1 ) and the crank shaft (8) does not oscillate. In this way, a compression process can be achieved in every 180 degree rotation of the crank shaft (8).
  • high compression rates can be achieved by connecting the lower parts of the pistons (1 ) to the upper part of the other piston (1 ).
  • the operating principle of the compressor with high compression rate for 0-180 degrees is seen. Its state is indicated at 0 degrees in the upper left, 45 degrees in the upper right, 180 degrees in the lower left and 90 degrees in the lower right.
  • the suction (A) and compression (B) regions are also seen at all angles.
  • the frictions that occur in the piston-cylinder region can be collected on the bearing systems and the friction losses that occur in such mechanisms can be prevented.
  • the lower part of the piston (1 ) can be used for suction (A) and compression (B) processes.
  • the number of pistons (1 ) can also be increased in order to eliminate the balance problems that may occur.
